We just discovered an issue in both 1.0.0.5 and 1.0.1.10 today which causes update of the store token required for accessing store repositories to fail. A fix for that has been pushed a few minutes ago: The update to version 1.0.1.12 you might be seeing on your device soon contains exactly this one fix to keep store access working.

My Jolla arrived this morning, and I've been playing with it all day. It is by far the most exciting device and operating system I've used in a long, long time. When it arrived, the first update to the operating system was already waiting for me to be installed - and only a few hours later, another update is hitting the device. They have promised another large bugfix and stability update before the end of the year, with updates with new features arriving early next year.

These men and women know what they're doing. They're not overselling, and they keep their promises. A very promising start.

HTML5 has it's advantages, but it is hard to predict what will happen.

Usually the open platform eventually wins, but it takes a lot of time and hard work, because the proprietary, probably closed and possibly native solutions are always first in a market. It takes time to create standards.

Have a look at for example what things Mozilla had to implement (a lot did not have a web standard yet):

You have to think of a solution, create it in a way which is portable and still flexible, supporting many different implementations or devices and screensizes. And propose that to the different W3C working groups for development as a standard.

Then other companies can join the effort to write a specification. They might have different ideas or priorities. So you'll have to collaborate.

Before you get to that stage you might be able to start to develop parts of the code, but you can't release your code as-is to the public yet. As the API isn't stable yet.

At the moment Firefox OS has a small following, but there are millions of webdevelopers and only 100's of thousands of iOS/Android developers.
